After thinking for a moment, Liu Hong asked, "Doctor Hua, do you know exactly how many bones are inside the human body?"

Hua Tuo was taken aback, then shook his head, "Your Majesty, I do not know!"

Liu Hong then asked, "Dr. Hua, do you know how human blood is produced? Is the blood of one person the same as that of another?"

"Your Majesty, I do not know!"

"Does Dr. Hua know how to distinguish the blood between people?"

"This...I don't know either!"

Liu Hong: "Dr. Hua..."

Hua Tuo: "I don't know..."

Faced with one question after another from the emperor, Hua Tuo could only sit there and shake his head dumbly.

Before coming to Deyang Palace, he was full of confidence that the treatment method he had created was unique. However, Hua Tuo now had deep doubts about himself.

Hua Tuo sensed that every question the emperor asked was closely related to his area of ​​expertise and was extremely important. Even if he knew and solved just one of the answers, he would gain insight into and enter a completely new level.

"Your Majesty's question is profound and unfathomable. I consider myself a skilled physician, but today I realize that my knowledge is merely superficial. I am truly ashamed to have failed Your Majesty's trust!"

Although the emperor only raised a few questions, they pointed Hua Tuo in the right direction. As long as he followed this direction, Hua Tuo believed that one day he would step into a higher and completely new realm.

Liu Hong looked at Hua Tuo with a solemn expression, "Yuanhua, there is no need to be modest. It is indeed great that you have discovered a new path in medicine. After all, opening up a new path is bound to be full of thorns. I hope that Yuanhua can continue to walk on it."

Hua Tuo, with a solemn expression, said earnestly, "Your Majesty, please rest assured! This is my lifelong goal, and I will certainly continue on this path, living up to Your Majesty's expectations!"

"Yes! Yuanhua, don't worry, I will prepare the tools and other things you need for the research!"

"Thank you, Your Majesty!"

In Hua Tuo's eyes, the emperor had become his teacher, and Hua Tuo was deeply moved by the emperor's trust and support. He looked at Liu Hong with great respect.

After Hua Tuo and Xi Zhicai left, only Liu Hong and Zhang Rang remained in Deyang Palace.

Liu Hong took out paper and pen, wrote a letter, and then handed it to Zhang Rang.

"This time you will personally go to Bingzhou. In addition to reading out my edict to Lü Bu, you must also keep an eye on those people's transactions. Not a single ounce of iron should flow into the grasslands."

"promise!"

"Hmm~ Also, find a way to bring back a few dozen slaves! They must be Huns or Xianbei!"

"This servant understands!"
